Answer:
The two sentences about what Mario does inside and outside the house are:
Dentro de la casa, Mario hornea el pastel y prepara las bebidas.
Fuera de la casa, Mario organiza y pone las mesas.
Translation.
Inside the house, Mario bakes the cake and prepares the drinks.
Outside the house, Mario organizes and sets the tables.
Present Tense in Spanish.
The conjugation of the verbs used in the sentences, taking into account the personal pronouns, is:
Yo: horneo / preparo / organizo / pongo.
Tú: horneas / preparas / organizas / pones.
Usted: hornea / prepara / organiza / pone.
Él: hornea / prepara / organiza / pone.
Ella: hornea / prepara / organiza / pone.
Ello: hornea / prepara / organiza / pone.
Nosotros / Nosotras: horneamos / preparamos / organizamos / ponemos.
Ustedes: hornean / preparan / organizan / ponen.
Ellos / Ellas: hornean / preparan / organizan / ponen.
Since the noun used in the sentences is Mario, which can be replaced by the personal pronoun "él," all the conjugations used belong to that pronoun.
